IMPROVED APPARATUS FOR CARBURETTING- AIR.

The Schedule referred to in these Letters Patent and making pan: Qt the same.

To all whom Iit may concern.

Be it known that we, J AMES F. Spalten, of Brooklyn, in the county of Kings, and-State of New York, and LOVIAS D. TOWSLEY, of Newark, in the county of Essex, andState of New Jersey, have invented certain new and useful Improvements in Oarburetters; and we-do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which make part of the same, and in which- Figure 1 represents a View, in perspective, of a carburetter embracing our improvements.

Figure 2 is a vertical section of the same,

Figure 3 represents a horizontal section through the gas-supplying reservoir, at the line x x of tig` 2.

Figure L repiesents a horizontal section ofthe apparatus, at the line y y of 2.

Ourinvention relates to au apparatus for carburetting air, applicable to gas-machines; and consists-in the construction of the 'carburetter in such manner as that the hydrocarbon-fluid will be supplied to the vaporizing action of the air in certain specific quantities, whereby we are enabled to utilize the entire body of hydrocarbon-fluid until the supply is consumed, and thus prevent the loss of a large proportion of the fluid, as is the case with carburetters heretofore constructed.

In the accompanying drawings- A is a cylindrical case, of any suitable dimensions, closed at both ends and hermetically sealed, within which is enclosed the tank B, for containing the hydrocarbon-fluid. This tank rests upon. the bottom of the enclosing-case A, and may be fixed or removable, at pleasure, and is of such dimensions as to leave an annular carburetting-chamber, O, extending from the bottom of the enclosing-case to the top ot'lsaid tank, and a chamber, 1),. of equal area with the case, above the tank, for the purpose of receiving, holding. and supplying the gas to the burners, which latter is done by means of a distributing-pipe, E. The tank is filled with the llydrocarbon-fluid, and the annular carburettingchamber C ofthe enclosing case is for the purpose of receiving from the said tank, so much of the hydrocarbon-Huid as is required for use, which is, at all times, a regular given quantity.

The interior suppl y-tank B is provided with a supply-pipe, l, at its upper end, communicating with an opening in the top ofthe enclosing-case, through which the tank is filled, and this opening is closed by a screwcap, G, .or any other suitable device.

The tank is also provided with a vertical tube, H, extending within a suitable distance of the bottom thereof, while its upper end communicates with the gas-supply chamber D. This tube H is for the purpose of 'equalizing the pressure upon the fluid within'- the tank, and insures a proper flow therefrom into the annular carburettil'ig-chamber C, through a pipe, I, at the bottom thereof, by a branch, J, extending through the enclosing-case A, communicating with said annular chamber C, and provided with a stop-cock, K, or its equivalent. rlhis stop-cock is necessary, in order to cut oti communication between the tank ,B and the annular chamber, when the tank is being filled, but is subsequent-ly opened, and remains so to allow the annular chamber to be regularly supplied. This communieating-tube I J must be on a level with the lower opening ot'the tube H, in thetank, audit is by this means that we are enabled to supply the annular chamber O with agiyen quantity of hydrocarbon-fluid, which is equal in depth to the space between the bottom of the case and the lower opening of said tube, and this quantity in thus limited the moment the fluid rises sutlciently in the chamber to seal the opening in the tube J, and is, at all times, the only portion of the fluid exposed to the vaporiziug action ofthe air, leaving the bulk of the material protected from such action, as shown in fig. 2, thus enabling ns to use the entire quantity until the tank is emptied, thereby effecting a great saving of material, which is lost, to a great extent, when the whole of said material is exposed.

In order to increase or diminish the quant-ity of hydrocarbon thus exposed, the vertical tube H is made adjustable, so as to increase or diminish the distance between its lower open end andthe bottom of the tank B, and thus increaseor diminish the iow of said material into the outer annular chamber'. This adjustment is eli'ected by a rod, a, passing through a stutngbox on the top ofthe case, and connected to the upper open end of the tube H, which may also pass through a stuiing-box in the top of the tank. The rod may have a scre\\'tl1read thereon, or may be held in position by the packing of the stuing-box.

The top of the annular chamber O is formed by au annular plate, L, hermetically sealed to the top of the' tank B, from which depends, asuitable distance, a series of tubes, M, communicating with the said annular chamber O, and also with the upper gas-supplying chamber l). 'lhey may be of any suitable number,

and are for the 'purpose of conducting the gas i'on'i the carburetting-chamber C t0 the supply-reservoir D, and may be filled with any suitable material which will conduct, by capillaryattraction, the gas to the supplychamber.

As the carburation of the air is eiected in the annular chamber O, 'in order-to increase the carburettingsurface of this chamber, it is provided with a corrugated or tinted cylinder, N, of any suitable material, such as wire gauze, 813e., arranged so as to enclose the series ot pendent vertical tubes M, by which the entire space of said chamber is utilized.

The air-supply pipe O, from the air-pump or Wheel, enters the gas-supply chamber D, and extends vertically a suitable distance into the annular carburet-tin gchamber C, through which pipe O the said chamber is supplied with a constant and'regular flow of air.

The carburetti11g-chamber G is supplied with one or more stop-cocks, l? Q, for the purpose of drawing o the iluid whenever'it shall become necessary or expedient, or to determine the quantity of the uid therein.

It' it may be deemed advisable, instead ot' the adjustable vertical tube of the tank, it may be provided with a coil.

Having described our invention,

We claim- 1. The carhnretter, having a fixed interior supplytank, B, anda xed surrounding carburetting-chamber, G, surmounted by megas-supply reservoir D, all arranged in the same vessel, communicating,r with each other, and operating lin the manner and for the purpose herein described and shown.

2. The tube I J, arranged at the bottom of the supply-tank, so as to communicate directly with the bottom of the annular carburetting-,chamber C, in combination with lthe supply-'tube H, for the purpose of supplying only so much Aof the hydrocarbon to be vapor-ized, as is equal in depth to the distance between the'open end of said tube H and the bottom of the tank, as herein described andl shown.

3. The series of.vertical tubes M, in combination with the annular carburetting-chamber 0, the corrugated open cylinder N, and the gas-supply reservoir D, arranged iu the manner and for the purpose herein described and shown.

4. The tube H, connected to and made adjustable within 'a fixed supply-tank, B, for the purpose ot regulating the quantity of the hydrocarbon within the car- .bnretting-chamber, irrespective of theI supply in the Witnesses:
